Abstract
Phthalates as esters of phthalic acid and aliphatic alcohol are environmental contaminants which are commonly observed due to their widespread use as plasticizers. Their chemical and physical properties allow them to migrate into the environment and also into foods and beverages easily. The objective of this paper is a summarized overview of phthalate properties, their impact on human health, their content in beverages, especially in beer, including the ways of contamination, and last but not least also legislative regulations.
Highlights
The EU issued a list of chemicals with proven or potential endocrine system disrupting activity, such as dibutyl phthalate, benzylbutyl phthalate, and bis(2-ethylhexyl) phthalate (DEPH) (Regulation (EC) No 1907/2006 of the European Parliament and of the Council)
The conclusion from this study indicates that there are no significant signs of phthalates content in beers stored in glass or aluminium bottles compared to cans (Carnol et al, 2017)
The Czech Head Public Health Officer set strict limits for phthalates expressed as a sum of dibutyl phthalate and DEPH in 1994
Summary
As phthalate-based plasticisers are not firmly bonded through covalent bonding in material, they are slowly released into the surrounding environment by volatilisation, leaching or migration (Wormuth et al, 2006) These compounds, have nowadays become ubiquitous pollutants in the environment (Wittassek et al, 2011). During brewing/fermentation, maturation and bottling of beer and wine, the liquids are in contact with tubes and joints made from plastic During their production, they are stored in large containers for a certain period that may last up to several weeks or months in case of wine, where maturation may be done in steel or coated concrete containers.
